Hi. To answer your question, yes and no. If it has R-12 in it, it needs to be removed, or, as we call it, evacuated. Then, you buy a new kit that has everything you need to adapt the R-12 fittings to the new style R-134A fittings. Then, after the system is empty, add th 134A. We do not recommend that you put R-134A into a system that already has R-12 in it. You could damage the compressor.

How do I convert from r12 to 134a cooling refrigerant in a 1992 Buick Lesabre?


I think you can still find the old R12 at a premium price. It would be worth it if your air con system holds well with no significant leaks. Genuine 12 Refrigerant LARGE SIZE 2 14 oz Cans
The old refrigerant and oil are not compatible with the new stuff. The expansion valve is questionable, may or may not work properly. The oil in the compressor, in the evaporator, in the condensor, and in the accumulator/filter/dryer need be removed thuroughly. New service port adapters are installed. Then the new R134 can be introduced. You may find a conversion kit with instructions.
I recall a bulletin calling for replacing the oil and reusing the refrigerant, repeatedly, 2-3X, the final oil replacement gets the new refrigerant.
When ever the system is exposed to the atmosphere, it should be evacuated before refilling. So much to think about and consider.

How to convert my a/c r12 to 134a my car is mercedes e300 1986


As far as I know you only have to change the compressor and dryer-filter to comply with 134a. Other components from old Freon 12 are safe to use for 134a. There's an Urban (mechanics) legend that you can use a 134a to an r12 system, but you can't use an r12 to a newer 134a system. But be on the safe side, change the compressor and dryer to use 134a or ask an expert on refrigeration.

Does anyone know how many cans of freeon it takes to charge the air conditioner


It depends on what size cans of freon you are getting and if the system has been retrofitted for R-134A refrigerant (1992 came originally equipped with an R-12 system). The factory specifications call for 1.8 Lbs. of R-12. If it has been retrofitted for R-134A, the general "rule-of-thumb" is 85% of the R-12 specification is needed to charge the system with R-134A. So if we do the math: 1.8 Lbs (R-12) X .85 (R-134A) = 1.53 Lbs. R-134A needed for a full recharge (providing the system is COMPLETELY empty. Then you will have to find out how much is in each can that you plan to buy and do the math to figure out how many cans you need. (some have 12 oz., some have 14 oz., some have 16 oz., some have 19 oz. and some have 22 oz.)

Where do I add the new r 410a refridgerant on 2004 Pontiac vibe?


410a cannot be used in a automotive system it will cause damage to your compressor, other other a/c components.
410a is used for home use only.as a substitute for R-22
see below definition.


Although the United States Environmental Protection Agency has mandated that R-22 along with other hydrochlorofluorocarbons (HCFCs) be phased-out in the United States, few window-mounted air conditioners are available that use R-410A. However, all of the largest central air conditioning systems manufacturers in the United States offer R-410A. As an alternative to window-mounted systems, a ductless "split" system is available which uses R-410A refrigerant, and can be installed with a 3-inch hole through the wall (or window opening).[4] R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in Japan and Europe.
Parts designed specifically for R-410A must be used as R-410A operates at higher pressures[5] than other refrigerants. Thus R-410A systems require service personnel to use different tools, equipment, safety standards and techniques.[6] Equipment manufacturers are aware of these changes and require the certification of professionals installing R-410A systems. In addition the AC&R Safety Coalition has been created to help educate professionals about R-41-A system.
manufactures recommendations for vehicle

NOTE:
  • R-134a is the only approved refrigerant for use in this vehicle. The use of any other refrigerant may result in poor system performance or component failure.
  • To avoid system damage use only R-134a dedicated tools when servicing the A/C system.
  • Use only Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or fitting seizure may result.
  • R-12 refrigerant and R-134a refrigerant must never be mixed, even in the smallest of amounts, as they are incompatible with each other. If the refrigerants are mixed, compressor failure is likely to occur. Refer to the manufacturer instructions included with the service equipment before servicing.

Where do you put freon into a 1992 Toyota corolla


You can no longer obtain R-12 type refrigerant for vehicles of that age. Do not use the "Over the Counter" type (recharge cans). They can cause component malfunction and will only last (if at all) for a very short period of time. If your system has not been converted over to R-134a, its time to visit your mechanic to have the proper conversion made.....Time to roll down your windows and get some natural AC going on :)

My air conditioner blows hot air, could it need freeon and if so where would I put it?


your system uses the old refrigerant type r-12 which is no longer available. you will have to get the system change overto the new refrigerant r-134a. it will cost loads of money.

Will I be able to put r-134a refrigerant frion in a 1992 acura vigor


I'm not sure if the system on that car is 134a or R12. There should be a decal under the hood that will tell you which one you are currently running, or on the compressor if it is easily visible. If it is an r12 system, you will have to buy a retrofit kit that converts the charge fittings to take 134a, as they are different size fittings.

Charge the ac on a 1992 ford explorer


first off you need to make sure you are using the right kind of refrigerant. older cars use r-12 refrigerant and must be converted to r-134a. if it hasnt been converted that would explain the failure of the fittings. go to the auto parts and ask them about the conversion. r-12 was very very bad for the ozone so they stopped using it. r-134a is bad... just i guess not as bad.

Air Condition


The low-pressure side recharge valve was changed with the conversion to 134 so it is nearly impossible to use the wrong stuff.

I found this discussion that indicates your car requires R-12 if it has not been converted:
